ESCO announces their new Commercial Truck TPMS System. The system is installed inside the wheel/tire cavity in the drop center of the wheel, giving a significant advantage over external valve stem mounted sensors that can easily be damaged or stolen. This system does not only measure the pressure of the tires but also the heat buildup in tires, which is one of the key factors in tire/wheel failure. In addition, the ESCO TPMS reads and records any abnormal air loss over a period of time due to a puncture or leak in the tire/rim.
